SPECIFICATION forming part Of Letters Patent No. 623,179, dated April18, 1899.

Application filed April 16, 1898. Serial No. 677,825, (No model.)

To (all whom it may concern:

Beit known that I, RODOLPHUS PEET, a citizen of the United States,residing at Escondido, in the county of San Diego and State ofCalifornia, have invented certain new and useful Improvements in(Hod-Crushers, Levelers, and Cultivators; and I do hereby declare thefollowing to be a full, clear, and exactdescription of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to a combined clodcrusher, leveler, grader, 850.;and it consists of the combination and arrangement of the several partsmore fully hereinafter described and claimed.

In preparing the ground for planting and other purposes as heretoforecarried on several independent machines have usuallybeen employed forharrowing, rolling or crushing, and grading or leveling, necessitatinggoing over the same surface a number of times corresponding to thenumber of machines used to attain the desired result, and as aconsequence the time and labor involved have been materially increasedand the operation rendered very tedious.

The object of the presentinvention is to provide a machine of thecharacter specified embodying the several devices heretofore operatedindividually for attaining at one operation a thorough preparation ofthe ground and obviating the inconveniences heretofore encountered whereseveral successive applications of different devices were necessary, andthereby lighten labor and reduce the expense of agricultural machineryof this class by unifying a number of machines in one.

' In the accompanying drawings, Figure 1 is a top plan view of theimproved machine. Fig. 2 is a similar view with a portion of the partsremoved. Fig. 3 is a longitudinal vertical section. Fig. 4 is a bottomplan view.

Referring to the drawings, wherein similar numerals of reference areemployed to indicate corresponding parts in the several views, thenumeral 1 designates the main f rame,c0mprising longitudinal end bars 2and transverse cross-bars 3 connected thereto. The end bars 2 areheavier than the said crossbars, and running parallel with and locatedbetween said cross-barsis a supporting-bar eler to serve as means forattaching the pivots. The rear lower portion 9 is beveled off toward thefront to reduce the lower edge, and a wear-strip 10 is secured over thefront and has its lower edge slightly depending below the lower edge ofsaid scraper or leveler. This construction is employed when the scraperor leveler is in the main formed of wood; but when metal alone is usedfor the same purpose the straps 7 and strip 10 will be dispensed with.In the rear upper part of said scraper an operating-platform 11- ishinged, as at 12, and freely extends to the rear over the supporting-bar4, the latter acting as a fulcrum for the operation of the scraper orleveler.

At the rear end of the frame a breaking-up or harrowing roll 13 ismovably mounted and has a series of teeth let therein, arranged atpredetermined regular intervals, and to operate this roll a lever 15 isconnected thereto and extends upwardly through the top of the frameadjacent the inner edge of the support 5 on the right, where a toothedlocking-plate 16 is located and adapted for use in holding the saidlever in adjusted position. Through the medium of said lever the roll 13is turned to bring the teeth in various positions and regulate the depthof penetration or entirely raise them from the ground.

Between the roll 13 and the scraper or leveler 6 a series of stationaryrolls 17 are secured to the under side of the frame, and in the presentinstance three are shown employed. The number of these rolls may beincreased or decreased, and when made of wood, as illustrated,preferably have a metallic covering 18; but it will be understood thatthe spirit of the invention would still be preserved if said rolls wereformed entirely of metal, and it is intended to so construct them, ifdesired.

Across the upper part of the rolls 17 extend diagonal braces 19 andreinforce and tie them together to resist strain brought to bearthereon. The said rolls serve as crushers or clod-breakers and arebolted to the end bars, as at 20.

Secured to the rearmost of rolls 17 are the lower ends of a guard-rail21, which extends upwardly and forwardly at an incline, being in themain above the top of the machine, and has a top cross-bar 22. is inconvenient position to be gripped by the operator, and thereby avoidaccident owing to the jolting and general uneven and irregular movementof the device. To the front central part of the machine a draft ring oreye 23 is shown for attachment of draft devices; but this is not anessential arrangement, as other well-known appurtenances could bereadily substituted therefor.

All the parts of the machine, or only a part of the same, could beconstructed entirely of metal, and in some instances wood alone might beused, and changes in the proportions, dimensions, and details ofconstruction could be resorted to without departingfrom the spirit ofthe invention or sacrificing any of the advantages thereof;

Under the circumstances wherein legitimate changes are contemplated thesalient features of the invention are preserved and the operation willbe as follows: The draftanimals are connected up to the front of theframe and the machine moved over the surface of the ground to betreated. The scraper or-leveler is brought into working position by theoperator disposing his weight on the platform 11, and'the degree ofpressure or penetration is regulated by the said operator movingrearwardly or forwardly on said platform. When a pressure is exerted onthe forward part of said platform, the lower edge of the scraper orleveler will be upon the surface of the ground. .The lumps or clods areleveled off by said scraper and the whole subsequently actedupon by thecrushing-rolls 17 and finally by the toothed breaking-up or harrowingroll 13. The function of the scraper, in the main, is to prepare theground in advance of and to be efiectually crushed by the rolls 17; butsome of the larger lumps or clods will necessarily be broken up bystriking said scraper. The roll 13 might not be needed at Thisguard-rail various times and can be quickly thrown out and to do thisboth the scraper 6 and the roll 13 will be thrown out of engagingposition. Thus it will be seen that several operations can be carried onat one time while the machine 1s traveling over the ground and thenecessity of separate devices for the same purpose is avoided, andconsequently I save time and labor and afford means for obtaining anexpeditious tillage of the soil.

Having thus described the invention what is claimed as new is- 1. In amachine of the character set forth, the combination of a frame, ascraper or lev eler at the front thereof, a platform hinged to saidscraper or leveler for operating the same, an adjustable rear toothedroll, a lever for moving said rear roll, and intermediate stationarycrushing-rolls.

2. In a machine of the character set forth, the combination of a frame,a scraper or leveler pivoted to the front lower portion thereof, atilting platform hinged to said scraper, a fulcrum-bar on which saidplatform rests, a rear adjustable toothed bar, an operatingle'verattached to said toothed bar, intermediate stationary crushing-rolls,and upper supports on opposite sides of said platform, one of which hasa toothed plate for engagement by said lever.

3. In a machine of the character set forth, the combination of a frame,a scraper and leveler at the front of the frame, an operatingplatformhinged at the front and extending rearwardly over the top of the centralportion of the frame, a fulcrum-bar on which said platform rests,stationary supports on opposite sides of and parallel with saidoperating-platform, a series of stationary crushing-rolls in rear of thescraper or leveler, a

guard-rail secured to the rearmost of said crushing-rolls and extendingupwardly and forwardly a rear adjustable toothed or harrowing roll, anda lever connected to said harrowing-roll and extending upwardly'throughthe top of the frame.

In testimony whereof I afiix my signature in presence of two witnesses.

RODOLPIIUS PEET.
